  23     description:
  24       List of supported frequency ranges in KHz. This can be used for devices
  25       that in a given config support less channels than normally. It may happen
  26       chipset supports a wide wireless band but it is limited to some part of
  27       it due to used antennas or power amplifier. An example case for this
  28       can be tri-band wireless router with two identical chipsets used for two
  29       different 5 GHz subbands. Using them incorrectly could not work or
  30       decrease performance noticeably
